Which action should an administrator take after realizing the incorrect patch sequence has been applied?

Reverting to a previous snapshot before applying the incorrect patch is an essential action in maintaining the stability and integrity of the system. When patches are applied in an incorrect sequence, they can lead to system instability, vulnerabilities, or conflicts within the software. By using a previous snapshot, the system can be restored to a known good state before the problematic patch sequence was introduced.

This approach enables the administrator to effectively roll back the changes that were made without having to manually uninstall each patch, which can be time-consuming and can potentially lead to further complications if not done correctly. After reverting to the safe state, the administrator can reassess and apply the patches in the correct sequence, ensuring that the system receives the intended updates without the risks associated with incorrect application sequences.

This corrective measure thus serves not only to restore functionality but also to enhance the understanding of patch management best practices, allowing for a more controlled and predictable environment moving forward.
